No sound but GarageBand with external speakers, Mavericks
I have a Peachtree Audio, digital amplifier, that always works. Since I have upgraded to Mavericks, I can only hear attached external speakers, if I unplug the cord in the digital out and replug it in. GarageBand will recognize DAC connection.
BUT no other sounds can be heard, internet, iTunes, etc... I tried selecting in sound / system preferences.
Hopefully I am doing something simply idiotic. I have GarageBand 09. GarageBand 11 is on the way in the shape of my new 13inch MacBook, but that takes a month. Don't see what it has to do with GarageBand, although it sounds like a software problem to me. Thanks in advance..
Simply I have no sound, but GarageBand.
